[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.

2008-03-25T19:39:55+00:00

Introduce per-sock inlines: sock_net(), sock_net_set()
and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set().
Without CONFIG_NET_NS, no namespace other than &init_net exists.
Let's explicitly define them to help compiler optimizations.

[IPV6]: Add ORCHID prefix to address label table

2008-02-29T04:55:02+00:00

Add a new label for Overlay Routable Cryptographic Hash Identifiers
(RFC 4843) prefix 2001:10::/28 to help proper source address
selection.

ORCHID addresses are used by for example Host Identity Protocol. They are 
global and routable, but they currently need support from both endpoints 
and therefore mixing regular and ORCHID addresses for source and 
destination is a bad idea in general case.

[IPV6] ADDRLABEL: Fix double free on label deletion.

2008-01-28T23:46:02+00:00

If an entry is being deleted because it has only one reference, 
we immediately delete it and blindly register the rcu handler for it,
This results in oops by double freeing that object.

This patch fixes it by consolidating the code paths for the deletion;
let its rcu handler delete the object if it has no more reference.

[NET]: Make rtnetlink infrastructure network namespace aware (v3)

2008-01-28T22:54:25+00:00

After this patch none of the netlink callback support anything
except the initial network namespace but the rtnetlink infrastructure
now handles multiple network namespaces.

Changes from v2:
- IPv6 addrlabel processing

Changes from v1:
- no need for special rtnl_unlock handling
- fixed IPv6 ndisc

[NET]: Modify all rtnetlink methods to only work in the initial namespace (v2)

2008-01-28T22:54:24+00:00

Before I can enable rtnetlink to work in all network namespaces I need
to be certain that something won't break.  So this patch deliberately
disables all of the rtnletlink methods in everything except the
initial network namespace.  After the methods have been audited this
extra check can be disabled.

Changes from v1:
- added IPv6 addrlabel protection

[IPV6] ADDRCONF: Support RFC3484 configurable address selection policy table.

2008-01-28T22:53:58+00:00

Policy table is implemented as an RCU linear list since we do not expect
large list nor frequent updates.
